WASHINGTON (AP) — U.S. Labor Secretary Marty Walsh is expected to leave the Biden administration to run the National Hockey League Players’ Association, according to two people familiar with his plans.

The hockey players’ union has been searching for a new executive director to take over for Don Fehr, who had been in charge for more than a decade. An association spokesperson had no official update on the situation when reached Tuesday.

A serious fan of the Boston Bruins, Walsh showed an encyclopedic knowledge of the sport in videos posted online during his tenure from 2014 to 2021 as mayor of Boston.

As labor secretary, Walsh helped broker a temporary work agreement between major freight railroads and their unions, preventing the risk of a strike that could have disrupted the U.S. economy ahead of the 2022 midterm elections.
